The peculiarities of explosive hardening (EH) associated with the impact of the shock wave on the metal are considered. Mechanical properties of Hadfield steel after EH are given. It is shown that intermediate layer of dry sand between explosive charge and treated metal provides amplification of the shock wave. This enables EH with the use of powdered explosives with low density and detonation velocity. The industrial technology of EH of railroad switch frogs is described. EH increases the service life of these parts by 20-30 %.
